Yeah, I agree with you. And I think a lot of people who are risk-averse for whatever reason are doing just that.
The risk of catching it because someone passes within a metre of you in the street or a shop is vanishingly small, assuming they don’t cough or sneeze or spit at you.
Of course everyone should be social distancing, but it is difficult for people to remain hyper-aware of the distance they are keeping from others at all times, particularly indoors and particularly if everyone is moving around. And we all have to be tolerant and considerate - social distancing involves two people!
I have also noticed that the people who get very self-righteous about social distancing are also often people who tend to behave in an incredibly inconsiderate way that forces others to come near them when they otherwise wouldn’t need to.
For example, I was queuing for a supermarket a few weeks ago. Three of us were allowed to go in - me, the woman ahead of me and the woman behind me. The woman ahead of us walked in and promptly stopped right after the entrance, in the middle of the aisle to start rummaging through the handbag. The woman behind and I both said excuse me, but she didn’t hear - so we both quickly scooted past her, about a metre away from her. She yelled ‘social distancing!’ at us. I said we couldn’t all go around the shop at her pace. And if she’d stepped to the side there would have been plenty of space for us to get round her.
If, despite knowing and understanding the risks, you are going to have a panic attack if someone accidentally steps within a metre radius of you, it’s best to avoid certain places and also best to be as conscious of your behaviour as possible - don’t stand in the middle of supermarket aisles, for example.
